MARINE TORPEDO.

SPECIFICATION forming part of Letters Patent No. 456,278, dated July 21, 1891.

Application file September 27, 1890. Serial No. 366,325. (No model.)

scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. V

This invention relates to the mechanical construction of torpedo-boats of the'class wherein the hull proper is submerged, but supported at a suitable distance below the surface by a float, the main objects of the invention being to provide for the protection of the float in case obstructions are encountered as the boat'is advanced in action, and

to provide for-the safe storage and support of the signal-lights; and to the ends named the inventionconsists, essentially, of a hull that is provided with a float and guard-arms that extend above the float and are adapted to supportsignal-lights.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar reference-figures indicate corresponding parts in all the views.

Figure 1 is a side View of a torpedo-boat embodying my invention. Fig. 2 larged view of the float, aportion of its arched support, and a portion of the float-guard, parts being broken away and parts being shown in section. Fig. 3 is a detail plan view of a portion of the float-guard- Fig. 4 is an enlarged central longitudinal sectional view of the forports.

ward portion of thetorpedo-boat, the view being given to illustrate the connection between the hull, the guard-arms, and the float-sup- Fig. 5 is a similar View of the stern of the boat, andFig. Sis a sectional plan View on line 6 Got Fig. 4.

In the drawings above. referred resents the hull, and 11 the float, said float being supported by arched bars1l2 and 12, that are rigidlysupportediii-castings 13 and 13. The float 11 is preferably formed of sheet metal and filled with any buoyant substance, such as cork or lamp-black. Just abaft the bow and justforward of the stern I a'rrns'14 and'14. e

From-the construction above described it is an en to, 10, reppivotally mount arms 14 and 14 that extend upward and over the float 1], theupper end ing formed with a hook or stop 16, which prevents the'arms' from separating. The arms 14 and 14 constitute a guard for the float 11,

and are normally upheld .by spring-arms 1.7

and 17, that are rigidly connected to the arched arms 12 and 12, each of these arms 17 and 17 being provided at its end with an anti-friction roller, as 18, said rollers bearing upon the under sides of the arms 14 and 14, and in order-that the spring-arms may be held from lateral displacementl provide each arm withlips 19, which overlap the sides of the will be seen-that if any floating obstruction-- depressed against the tension of itsspring 17 and will be gradually carried downward, the

- momentum of the boat being gradually checked and the movement of the two arms 14 and 14 being suflicient to permit of their movingclose down upon the float-supports 12 and 12, and consequently the boat will pass forward beneath the obstruction.

v In case operations are carried on at ,night it is desirable that some provision be made for tracing the course of the boat; and tothis.

end. I mount signalrlights e e beneath the I guard-arms 14 14, and I find in practice that this arrangementhas. many advantages over the ordinary signal-staff employed in other submarine torpedoes.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is r 1; The combination, with the hull of a torpedo'boat, of a float connected thereto and a yieldingly-mounted guard-arm that extends from the hull upward and above the float.

Q, 2. The colnbination, with the hull of a tor pedo-boat, of a' float arranged directly above said hull and yieldingly-mou'nted guard arnm that extend from the hull over and above rho The combination, with thehull of a tor" pedo-boat, of a float rigidly connected there to and yieldingly-mounted guard-arms that extend from the hull upward and over the float. I

4. The combination, with the hull of a torpedo-boat, of a float connected thereto and yieldingly-mounted guard-arms that extend from the hull upward and over the float and interlock at their upper ends.

5,. The combination, with the hull of a terpedo-boat, of a float connected thereto, guardarms that extend from the hull above the float, and springs arranged in connection with the guard-arms.

6. The combination,wit-h the hull of a tor-- pedo-boat, of a float connected thereto, guardarms that are pivotally connected to the hull ends and extend upward and over the float and interlock at their upper ends, spring-arms carried by the float, and anttfriction Wheels carried by the spring-arms and arranged to bear on the'guard-arms, substantially as described. v

7. The combination, with the hull of a terpedo-boat, of a float connectedlthereto, guardarms that are pivotally connected to the hull ends and extend upward and over the float and interlock at their upper ends, spring-arms carried by the float, anti-friction wheels carried by the spring-arms and arranged to bear on the guard-arms, and lips also carried by the spring-arms and arranged to overlap the sides of the guard-arms.

8. The combination, withthe hull of a terpedo-boat, of a float connected thereto, a 5

thereto, a metallic float carried by the arms and filled with a buoyant material, such as cork, guard-arms that extend above the Heat, and springs arranged in connection with the guard-arms.

10. The combination, with the hull of a terpedo-boat, of a float connected thereto. yieldingly-mounted guard-arms that extend from the hull upward and over the. float, and signal-ligh ts carried by said arms.

In testimony whereof I affi x my signature in presence of two witnesses.
